❖Communication practices: Principle 1 Listen: •Try to focus on the speaker‘s words, rather than formulating your response to those words. •Ask for clarification if something is unclear, but avoid constant interruptions. •Never become contentious in your words or actions (e.g., rolling your eyes or shaking your head) as a person is talking. Principle 2 Prepare before you communicate: •Spend the time to understand the problem before you meet with others. If necessary, perform some research to understand business domain. •If you have responsibility for conducting a meeting, prepare an agenda in advance of the meeting. Principle 3 someone should facilitate the activity: •Every communication meeting should have a leader (a facilitator) 1)To keep the conversation moving in a productive direction, 2)To mediate any conflict that does occur, and 3)To ensure that other principles are followed. Principle 4 Face-to-face communication is best: •It usually works better when some other represen...
What is Java Virtual Machine and Command Line Arguments
Java Virtual Machine
All language compiler translate source code into machine code for a specific computer .Java compiler also does the same thing ,Then how does java archive architecture neutrality ? The answer is that the java compiler produces an intermedia code known an bytecode for a machine that does not exits , This is a machine is called the java virtual machine and it exits only inside the computer memory , It is a simulated computer within the computer and does all major machine of a real computer, illustrates the process of compiling a java program into byte code which is also referred to as virtual machine code
The virtual ma chine code is not machine specific code (known as machine code) is generated by the code interpreter by acting as an intermediary between the virtual machine and the real machine as shown in Remember that the interpreter is different for different machines.

Illustrate hoe java work on a typical computer , The java object framework (Java API) acts as the intermediate between the user the virtual machine which in turn acts the intermediary between the operating system and the java object framework
.Command Line Arguments
There may be occasions when we may like our program to acts in a particular way depending on the input provided at the time of in the executions . This is archived in java program by using what are the known as command line argument , command line argument are para meter that are supplied to the application program at the time of invoking it of execution , It may be recalled that program was for invoked execution of the command line
.Here, we have not supplied any command line argument. Even if we supply argument, the program does not know what to do with them.
We can write Java programs that can receive and use the argument provided in the command line. Recall the signature of the main ( ) method used in our earlier example programs:
As pointed out earlier, is declared as any array of string known as string objects .Any argument provided in the command line at the time of execution are passed to the array its elements , We can simply access the array element and use them in the program as we wish .

What is Relational structure, Table, Attributes, Rows Record, Domain, Super key, Composite key, Candidate key, Primary key, Foreign key
Table:- The table in a database has it unique name in the relational in table consisting Horizontal rows that is also called as Tuple s fore the Vertical columns also called as attributes. Each table row represent a single entity Occurrence withing the entity set. Attributes:- In the above table column represent data stored in it such column is called as attributes. Ex-Name id (column name) every cans a table must have at least one column. The squle standard does not be specify in in only maximum number of column in a table. Rows Record:- In a single row in a relational table which contain all information about. A single entity each horizantal row of student table represent the student record and in the and table there are multiple row. Domain:- The every column in a table has set of data values that are allowed for that column that is called as domain. In a relational table a domain can have a single value or null values .Type...

What is DDL --Data Definition language and DML -Data manipulation language
DDL --Data Definition language DML -Data manipulation language DDL --Data Definition language:- To create alter drop the table in or database we use data Definition language. The DDL command is used to built or modify the structure of a database or a object in that for the database object are any data that store and create in database For-tables, Rows and View 1.Create Command 2.Alter Command 3.Drop Command 4.Rename Command 1.Create Command:- To create database objects like table or modify database we used create command, The create statement is use to the create any types of objects. Syntax-Create table table name (column 1 data type (size), Column 2 datatype (size) ). Create table students (Id int , name varchar (255)); To view the create structure we use describe command " describe the table name. 2.Alter Command:- One there table or database create we required to change a structure of the database or class object we use into the alter comm...
